#ifndef SHARE_UTILITY_ATTRIBUTENORETURN_HPP
#define SHARE_UTILITY_ATTRIBUTENORETURN_HPP

// Provide a (temporary) macro for the [[noreturn]] attribute.
//
// Unfortunately, some older (though still in use) compilers have bugs when
// using [[noreturn]].  For them we use an empty definition for the attribute.
//
// Note: This can't be placed in globalDefinitions_xxx.hpp because the
// attribute is used in debug.hpp, which can't include globalDefinitions.hpp.

// clang 12 (and possibly prior) crashes during build if we use [[noreturn]]
// for assertion failure reporting functions.  The problem seems to be fixed
// in clang 13.
